I never cease to be amazed by portals in video games. Even though the tech is nearly two decades old (and older still, if you include the use of portal rendering for hidden environment transitions in Thief and other early 3D games), Portal's seamless, real-time transitions through holes in space still feel like magic to me, and I love seeing it appear in other games too. One of the better uses of portals lately can be found in Marvel Rivals, where if you're playing as Doctor Strange, you can conjure portals in thin air and drop your entire team of superheroes on the heads of your foes.
It's a fantastic effect which, as explained by Rivals' technical lead designer Ruan Weikang, was extremely difficult to pull off. Weikang recently spoke to Epic Games about how NetEase used Unreal Engine 5 to recreate an Avengers movie's worth of superheroes, and he referenced the good doctor's space-folding abilities as one of the trickiest powers to replicate.
